  • Patent number: 4664641
    Abstract: This box type turkey call features a laterally moved actuator contacting the sides of a box. The actuator is mounted on a rotatable mounting. Attachment is eccentric on the mount. The mount, on the opposite surface, is slotted to accept a tool to affect movement of the attachment as the mount is rotated. This movement of the point of attachment enables this box call to produce a variety of different calls, each of which may be finely tuned, and to compensate for wear.
